Notes. Listed: μ positions, the total observing time of all spectra of the corresponding μ (e.g. 17 single spectra add up to 170 min of observing time), and the S/N of single spectra. Errors: Maximum pointing position offset Δvpoint., velocity dispersion among spectra σscat, the maximum rotational velocity offset Δvrot, and the line accuracy ΔvLARS, 6175.
